Spiro Agnew resigned from the office of Vice President in 1973 due to allegations of tax evasion and bribery related to his time as governor of Maryland. Gerald Ford was appointed as his replacement and later became president when Nixon resigned, marking the first time the 25th Amendment was used to fill a vice presidential vacancy.
Resignation of Vice President Spiro Agnew:
Vice President Spiro Agnew was forced out of office in 1973 due to a scandal involving tax evasion and accepting bribes while he was the governor of Maryland. Agnew resigned from his position in October 1973 amid the unfolding Watergate scandal that threatened the Nixon administration.
Following Agnew's resignation, under the terms of the 25th Amendment, President Nixon appointed Michigan congressman Gerald Ford as vice president, who later became president when Nixon resigned.
It is noteworthy that Ford's appointment was a historic moment as it was the first such appointment under the 25th Amendment, making him the first person to become vice president, and later president, without being elected to either office.
Following Ford's ascension to the presidency, he chose Nelson Rockefeller as his vice president, also under the provisions of the 25th Amendment.
